3 hough the Emmy Award winning VPR-3 is a marvel of technical achievement, the most significant achievement of the VPR-3 is what it can accomplish for you, especially in the areas of editing, animation and program compression TURBO (Rea1-time) Animation The VPR-3's speed and accuracy allows it to do animation in a playspeed, real-time relationship Unlike stationary mode recording, the VPR-3 does not require the complex (and often picture-degrading) preprocessing of the video signal to rearrange the video frequencies before recording The VPR-3's playspeed recording is purely a video edit With an 18 frame pre-roll, 3 frame post -roll and a re-cue, the VPR-3 can accomplish a 6 frame animation sequence in only 16 seconds (required for 1 cell) plus only a tenth of a second longer to complete the remaining 5 frames! For The First Time, True Auto- Assembly With Field Accuracy The combination of a 20 millisecond lock-up time, 500 inches/sec2 acceleration, and speed transitions comparable to disk devices allows a 30 second spot to be recued-to-play in less than two seconds The VPR-3 brings to editing the super-fast speeds required for uninterrupted recording of source material You can perform single-field edits from the front panel or from the serial port (The VPR-3 is the only VTR capable of searching to a field) Edits will be dead-accurate because a built -in SdH circuit gives the VTR immediate comparison between the input and the off-tape signal phasing, therebyensuring perfect frame edits The time consuming process of test edits, adjust - ments, and re-edits becomes a thing of the past When there is a mismatch between input and off-tape signals, the VPR-3's SdH phasing control allows the operator to apply an offset for correction (And to make editing even easier, an indicator just above the Sc/H meter shows the operator that a wrong frame edit is being attempted) The VPR-3's machine-to-machine editing capability from a single machine control panel eliminates the requirement for an expensive exter - nal edit controller in many facilities The combination of the full-time synchronized transport and the SMPTE communication bus is the basis for this exclusive feature Even the most complex split edits can be previewed, trimmed, shifted, performed and then reviewed using only the simple, single-function controls on the record VPR-3 4

4 Key Features Of ZEUS Processing D No compromise 4Fsc, 9-bit digital system D Drift and adjustment-free velocity compensation dramatically improves compensation accuracy and multi-generation video performance D Exclusive frame averaging velocity compensator function reduces head impact error visibility D Superior spatial-averaging dropout compensation D Exclusive Multi-Gen Setup mode greatly improves multi-generation video performance D Unique Decode mode allows replay of non-color framed edits with no picture shift D Video time compression and expansion with no picture bounce or blur D Full frame storage on command D Comprehensive interface with VPR-3 menu control system D Available full-function serial remote control panel sequence that quickly duplicates 10 tape generations This 10-generation sequence is continuously repeated, so that errors are clearly displayed, and can be quickly corrected by proper system adjustment Multi-Gen Setup supports an increase in both the number of tape generations routinely used, and the quality of the finished video product Multi-Gen Setup The VPR-3/ZEUS Multi-Gen Setup mode helps eliminate operational setup errors-a major contributor to multi-generation performance degradation Multi-Gen Setup is accomplished through a series of playrecord-play-record recirculations through the VPR-3 and Zeus processor From pre-recorded lst generation reference material (ie, color bars) the VPR-3/Zeus system generates and displays, in real-time, a 5

5 Tape position accuracy in TV lines, instead of fields Tape tension differences reduced from the typical %, to 4-5%: Easy to say, difficult to do-so difficult that the VPR-3 stands alone in the industry at this performance level Vacuum Capstan With High Resolution Tachometer The precision-ground vacuum capstan is directly coupled to a low inertia, high torque DC motor assembly This system allows the tape to be controlled from zero to :!: SOx play speed in a single function without tape stretch or damage The optimum tape coupling obtained with vacuum allows the use of a high resolution integral tach instead of a separate, and less accurate, tape timer assembly This ultra-high resolution tachometer is accurate to within 12 television lines, providing parking accuracy superior to all other C- format VTRs Continuous capstan control of tape motion also permits the use of a coupling servo to adjust capstan acceleration to take advantage of the VPR-3's high torque reel motors ~ ~ ~ ~ -- ;;;,- 1 ~:~ :-L~- I, I I I Vacuum Capstan 2 Flutter Idler Air Guides Roller Guides Fixed Roller Guides ~ 6

6 Low Friction Tape Path And Active Guide System A configuration of gas-film guides at critical locations, plus precision rotary guides, reduces the effects of friction permitting very rapid changes in tape direction, regardless of temperature and humidity conditions, or tape formulations This low friction, active tape guiding system provides constant tension and allows almost limitless high speed shuttling It also dramatically reduces head and scanner wear, and allows reel sizes from spot to 3 hours to be used while maintaining gentle and precise tape handling Servoed, Fail-Safe Dynamic Braking The VPR-3's advanced design completely eliminates the marginally effective mechanical brakes often used in VTR transport design In the event of power failure, even at full shuttle speeds, the VPR-3's servo system brings the tape to a smoothly controlled stop, eliminating the possibility of tape damage Field Rate Color-Framer An integral part of the video signal system is a field rate colorframer which determines the precise parking position when the tape transport is stopped This colorframer is designed to separate one field out of four in the NTSC system or one field out of eight in the PAL system This permits the machine, even with its "instant" start capability to operate in a fully synchronous mode at all times Microprocessor-Based Control The VPR-3 control system is based on dual Z80 microprocessors One of these processors is responsible for system control and the second controls the various input/ ouput functions The dual RS-422A serial communications ports allow control interface of the VPR-3 to a variety of serial machine controllers, including the Ampex ACE series editors and the VRC-2 A Unique, Field-Accurate Automatic Scan Tracking (AST TM ) System Taking a precision reference from the direct -coupled capstan tachometer, the VPR-3's AST system knows exact tape position under all conditions and applies the necessary correction factors to produce a stable, disturbance-free picture In the time compression and expansion modes, this system allows speed variations as small as one second per hour (up to:!: 15%) to be entered 7

7 less of the application, an extremely powerful control system with equally powerful software is necessary to make it easy to use The control system described on these pages accomplishes just that Menu-Based Operational System The VPR-3's menu-based control system eliminates the tens of dedicated keys that would normally be required to accomplish VTR set -ups, editing function, cueing, animation, etc This soft key approach maintains the VPR-3's incomparable operational flexibility; while providing aneasy-to-learn, fast-touse control panel that is optimized to your specialized needs With the user set up menu, you can store all the functions required for any one operation, and then recall them with a single keystroke A complete operational environment can be created in this way; minimizing the time consumed in major VTR application changes 8

8 Status-At-A-Glance TM Displays As a further enhancement of the VPR-3's operational interface, its Status-At-A-Glance system provides a summar}; one page, English language video character display of all critical VTR operational status parameters A second page displays all major ZEUS operational parameters Either page may be easily selected for display on the VTR video monitor 9

9 he VPR-3 is as sophisticated as it is versatile and powerful High perfonnance editing, superb animation and smooth program compression/expansion are supported by the hundreds of circuits, components and assemblies that are required to do the job-with no compromise So along with this high perfonnance and versatility, Ampex gives you the tools you need for quick, easy servicing The home menu (and the video monitor) displays fault conditions as well as non-standard conditions, allowing the operator to quickly identify abnormal operational conditions Power-up diagnostics check computer buses, power supplies and microprocessors to confirm operational status Then, continuous diagnostics take over to check tape path conditions and all operational environments The operator is informed if faults are found, and then board and chip level diagnostics are used to isolate the fault 10

10 Easy Accessibility Straightforward access to circuit boards is obtained while maintaining full control panel operation Most of the VPR-3's circuit boards are located behind a swing-down control panel that quickly moves out of the way for extender board mounting of circuit boards Circuit boards plug-in to two mother boards, permitting "instant" board replacement when the diag- nostics so indicate All major servo drive and power supply components inside the VPR-3 are located on plug-in assemblies for quick replacement or repair The servo and power supply card bay can be hinged down for easy access to the rear of the tape transport and the internal air/ vacuum system Optional Accessories A number of accessories and options are available from Ampex to expand the operational capabilities of the VPR-3 These may be pur - chased with the machine, or added later as operational needs change They include: D Sync Channel An option to permit all vertical sync information to be recorded according to the SMPTE/EBU Type C formats D Four Channel Audio This EBU option provides a fourth high quality audio channel in the track space normally allotted to the sync channel D Mounting Configurations The VPR-3 is available in a variety of physical configurations to suit individual facility requirements 11
